Hi Op - I have a son who is allergic to dairy and he was diagnosed at 9 weeks of age. I was breast feeding so removed all dairy from my diet and the general rule is that it takes 6 weeks before the baby’s system will be clear of dairy so to allow this length of time for an improvement.
The term dairy intolerance is no longer used becsuse if a baby can’t have dairy they are allergic to it, not just intolerant. The term “allergic” used to refer to an anaphylactic type reaction whereas the “intolerance” term was used to label the other symptoms like vomiting, diarrhoea, reflux, eczema etc etc. They are all now under the same unberela of any allergy to the protein regardless of how the reactions presents.
A lot of people get confused with lactose free and dairy free and believe them to be the same thing. My husband once came home with lacto-free butter because he thought it would be okay and I had to explain to him that our son was allergic to dairy, not lactose.
Also - soya proteins are very similar to the proteins in cow’s milk so most breast feeding mothers have to remove soya out of their diet as well as milk.
Most baby with allergies also have reflux and require medication for it, usually ranitidine or omeprazolr, so it may by worth speaking to your GP about that to control the pain.
Please don’t give your baby normal formula because if she does have an allergy then it is likely to cause her so much pain and lead to a lot of problems. If your baby can’t handle dairy via your breast milk then the repercussions of her having it directly can be quite severe.
My CMPA son is 16 months old now and on Thursday my father in law decided to give him a few Maltesers as “a treat” (his words) and my son is still paying the price 3 days on. It started with the stomach pains and cramps on Thursday night, crying for hours on end, woke up Friday with an horrendous cough, sneezing, running nose, big circles under his eyes (typical reactions to dairy) and very unhappy. On Saturday he started with the vomiting and the bad nappies and he’s barely eaten all weekend because of his stomach pains. The reason I’m awake now at 3am is because I’m up with him still writhing around and whimpering with stomach cramps, it’s heart breaking.
If you want formula then either pay for it (Nutramigen, Neocate or Aptamil Pepti) or see your GP for a prescription.
